Convergence problem for the surface complexation model
Dear Sir or Madam,
Sorry to disturb you. I am Lang. I created a 1D transport model with surface complexation. I found it could not achieve convergence, while it worked if I attempted to increase the S_AREA (surface area for sorption). Is there anybody can explain me what is wrong?
Additionally, I am not clear about the difference between AMIN (initial specific mineral reactive surface area) and S_AREA (surface area for sorption). If I only know the value of specific surface area for the specific mineral associated with sorption, which one should this value be (AMIN or S_AREA)? Thank you!
Best regards,
Lang
